Specification of Letters Patent. Patented Aug. 23, 1921.

Application filed June 14,-1919. Serial No. 304,209.

To all whom it may concern."

Be it known that we, SAMUEL E. MORRAL and TILLIAM W. MORRAL,; citizens of the United States, residing at Morral, in the county of Marion and State of Ohio, have invented certain new and useful Improvements in Corn-Husking Devices, of which thefollowing is a specification, reference being had therein to the accompanying-drawing.

This invention relates to corn husking devices and more particularly to ear removing deviceswhich are used in connection with the husking devices. The object of the invention is to provide a device of this kind with means for delivering a stalk of corn, with the ear attached, to the device which removes the ear from the stalk; and which will properly position the ear with respect to said removing device.

A further object of the invention is to provide such a device which will separate the ear from thestalk and deliver the ear to the husking devices without mutilating the stalk. i

A further object of the invention is to provide such a device which will be simple in its construction and operation and which can be produced at a relatively low cost.

In the accompanying drawings Figure 1 is an end elevatlon' of a corn husking'machine embodymg our invention; Fig. 2 1s a side elevation ofthe same, with the platform removed; Fig. 3 is a plan view of such a machine; Fig. 4 is an end elevation of.

a machine embodying the invention in a slightly modified form; Fig. 5 is a plan view of the machine of Fig. 4; Fig.6 1s an end elevation of a machine embodyin a further modification of the invention; ig. 7 is a plan-view of the machine of Fig. 6; and Fig. 8 is a detail view of the ear removing device of Fig. 7. v

In Figs. 1 to 3 of these drawings we'have illustrated one form of our invention and have shown the same embodied in a corn husking machine comprising a main frame 1 upon which are. mounted earremoving devices 2. 'These ear removing devices are arranged at a'point remote from the forward edge of the frame. and substantially midway between the ends thereof. The operators station is in front of the machine and the frame may, ifdesired, be provided with a supporting bracket 3 to support a quantity are in the form of snapping rollers and the conveyer for the stalks of corn comprises two oppositely rotating rollers 4 and 5 which are connected with the respective snapping rollers for rotation therewith. The rollers 4 and 5 are arranged one above the other and, in the present instance, provided with spiral ribs forming grooves, which engage the stalk of corn and move the-same lengthwise of the conveyer rollers toward the snapping rollers and at the same time move the stalk transversely of the conveyer rollers to bring the butt of the car into engagement with said rollers so that it will be in a proper position to be engaged by the snapping rollers when the stalk has reached the end of the conveyer rollers. The

conveyer rollers may be arranged in various ways, but in this form of the device the upper roller 5 is somewhat shorter than the lower roller and has its outer end suspended above the lower roller and tapered so that a stalk of corn may be placed over the lower roller and moved between the two rollers into a position to be engaged by both rollers.

In thepresent construction the outer end of the upper roller is not provided with individual supporting means, but is supported solely by the hearing or bearings for the op posite end thereof. The main frame is provided with a table top 11 extending on opposite sides of the conveyer rollers to support the ends ofthe stalks of corn.

The conveyer-will move the stalks bodily across the table, but we prefer to provide supple- -menta1 conveying means to move the ends of the-stalks so asto maintain each stalk in a substantially straight line. As here shown, thesupplemental conveyors comprise sprocket chains 6 having fingers 7 and extending'about'sprocket wheels on shafts 8 arranged along the front and rear edges of the table and so mounted that'the upper stretches of the conveyer chains will lie beneath the tabletop and the fingers 7 will compartment 9 in which the stalks of corn are bunched. The separated ear drops throu h an opening in the table top, which is bro en away in Fig. 3 and is delivered to suitable husking devices which are here shown as husking rollers 10. These rollers are arranged'in an inclined position beneath the table top and act upon the ears of corn in a well known manner to separate the husks therefrom.

Any suitable driving mechanism may be provided for operating the several parts of the machine. As here shown, a main driving shaft 12 is mounted in the lower part of the frame 1 and has secured thereto a belt pulley 13.- This shaft 12 is connected at one end by suitable gearing with a vertical shaft 14 which, in turn, is geared to the lower conveyer roller 4:. At its opposite end the shaft 12 is connected by suitable gearing with a vertical shaft 15 which, at its upper end, is geared to the end of a shaft 16 forming an extension of the upper conveyer roller 5. The conveyer chains 6 are driven by means of a vertical shaft 17 gearedto the driving shaft 12 and to the conveyer shaft 8.

'The husking rollers 10 are connected one to the other at their upper ends by spur gears 18 and one of the rollers is connected by beveled gearing with a shaft 19 journaled in a frame 1 and driven from the driving shaft 12 by a sprocket chain 20.

In Figs. 4 and 5 of the drawings we have illustrated a slightly modified form of the invention and have shown the same as comprising a frame 21 having mounted thereon and extending transversely thereof two conveyer rollers 22 and 23 arranged one above the other and having secured thereto'at one end thereof snapping rollers "24:. These rollers are carried by the shafts 25, to which the respective snapping rollers are also secured, and which are journaled at their in ner ends on theframe 21 and are connected one to the othervby spur gears 26. One of these shafts extends beyond the spur gear and has secured thereto a belt pulley 27. The .outer end of the shaft of the lower roller 23 is journaled in a bearing 28" on'the frame member and the outer end of the shaft of the upper roller 22 is journ'aled in a bearing 29 formed at the outer end ofa bracket or arm 30 supported near theopposite side of the frame 21, extending transversely thereto and havin its outer end unsupported and spaced to leave an open space at the end of the conveyer rollers, beyond the snapping rollom the bearing 28 so as ers, through which the stalks of corn may pass. lVith this type of machine stalks of corn are fed end first into the conveyer rollers which move them longitudinally to bring the cars into engagement with the conveyer rollers and then move themtransversely, that is, lengthwise of the conveyer rollers, to bring the ears into positions to be engaged by the snapping rollers ears, have been removed the stalks are delivered in a pile at the side of the frame and the ears may, if desired, be delivered to husking devices arranged beneath two snapping rollers in the same manner as described in eonnectionwith that form of the machine After the frame from the operators station to the snapping rollers. l/Vith this construction the stalks are placed on the conveyer 33 at the receiving end' thereof and are moved transversely to bring the cars into engagement with the snapping rollers which remove the ear and deliver it to the husking rollers, and the stalks are then delivered in a aile as before described. roller is mounted on the main frame 33 while the upper roller is carried by the'end of an arm. 34 which extends from the rear edge of the frame and supports the upper snapping roller in such a manner that it will not interfere'with the passage of the stalk between the two rollers. The snapping rollers and conveyors may be driven in any suitable manner. As here shown, they are The snapping driven by suitable sprocket chain connec tions from the main driving shaft. 35.

The operation of the'invention, in the several forms shown, will be clearly understood from. the foregoing description, and it. will be apparent that we have provided very simple mechanism for moving stalks ofv corn to the ear-removing devices and for so posishown as mounted on a stationary frame, it i will be entirely obvious that this frame could be mounted on wheelsand conveyed from point to point.

While we have shown and described'cer tain embodimentsof the invention, we wish it to be understood that We do not desire reassess to be limitedto the details thereof, as va-- rious modifications may occur to a person skilled in the art.
